18 x Ultra Bright Blue LED Emergency Warning Flashing Strobe Light Bar for Windshield & Dash Grille - Perfect for Police, Security, Construction & Emergency Vehicles

No problems with this product if your are moderately handy/ tech savy. Tips: I securely reinforced all the wire junctions (male/female clips) with electrical tape to prevent them from getting pulled out over time. Also to mount the LEDs to the top of my windshield I went to my local hardware store and bought adhesive picture frame clips, stuck the clips to the bracket, and the lights clipped right into the top of my windshield and displayed PERFECTLY (clipped onto the fabric of the interior roof of my car) no bolts or screws. 10/10 for the price can't beat it. Used the lights for a motor vehicle accident call within 5 min of finishing installation (total install about 30 min) Looked good on scene. FYI you need an accessory power line installed to avoid real headaches (I already had one installed previously by a local car stero shop). Second best would be a splice from a cigarette lighter for power.
